Researchers from KAIST (Korea Advanced Institute of Science and Technology) developed it DCRS a system wireless charging, which is able to charge up to 40 smartphones simultaneously, from a distance of 5 meters.
The system is called DCRS (Dipole Coil Resonant System) and for the mode it uses magnetic fields that carry electricity. KAIST's system is based on the CMRS (Coupled Magnetic Resonance System) first introduced by MIT in 2007.
However, the Dipole Coil Resonant System created by the Koreans, incorporates a series of elements that allow the commercial exploitation of the system, unlike the earlier CMRS.
Basically points of differentiation and improvement is the complex structure of the coil that requires four coils, the overall size and the most efficient energy transfer.
The structure of its spirals Dipole Coil Resonant System consists of two magnetic bipolar coils. The primary coil causes the magnetic field and the secondary coil receives the electricity.
The system is compact in size and staggered can achieve power output up to 209 Watt at frequency 20 kHz.
Although similar systems have been developed by other researchers, even with a larger range, the KAIST system is the only one capable of charging so many devices at the same time.
In fact, its creators believe that their system has enough power to be able to charge even larger devices such as televisions and computers.
